Works for most vehicles

Pretty impressive with many features . Unfortunately Can not decode newer Mazda vin , no support for Volvo xc40 at all.

Not bad, but not the best I’ve used on iOS

Not a bad scantool. Does everything it says it does. So I can’t be mad.
If i had to complain, it would be that the tool has zero transmission adaptations. If they atleast added support for this feature, I’d be willing to call it the best out for iOS.
Also, no online coding/programming. This scantool has a close cousin out there and that tool has these features but the iOS version is a little broken so overall the TopGuru is a more stable option for us iOS users.
Also, if you want the TopScan Pro, buy it directly from Topdon. I have never seen it for sale anywhere else and the price is right!

This is a very capable and useful tool. I hav used it several times and was impressed by the amount of things it can do. Bidirectional control complete system pre and post scan included. Now it’s not perfect has some glitches and sometimes all the functions don’t work on a particular application but they do updates often and I think they really try to make it better all the time. I think it’s a great option for the home diy to a professional tech, the dongle nice but I recommend you find a lanyard or something to put on it it’s easy to forget. Great option for the price
